Pulley cheek manufacturing
Habr, Stanislav ; Císařová, Michaela (referee) ; Peterková, Eva (advisor)
This bachelor thesis focuses on the technology of follow cutting. The purpose is to project a progressive press tool for the given component of a pulley cheek made of a stainless steel sheet with the thickness of 1 mm. The optimal variety of component production was set on the basis of the theoretical study in the first part of the project. The progressive press tool uses standardized components and it is realized by using the usual post which is fixed to the compressing machine LEN 63 C (producer TOMA Industries Ltd.). At the end of the thesis, there is an economic assessment of production of the annual batch of 200 000 pcs.

Proposal pressing tool for sheet metal part
Ručka, David ; Peterková, Eva (referee) ; Špaček, Jindřich (advisor)
The in the framework of Bachelor Studies developed project presents a technology- proposal for the production of a pressing tool for the manufacturing of parts from the sheet steel S500MC. On the basis of a literary survey of problems of the component manufacturing through shearing and calculation, cutting in the phase-shearing tool was proposed. According to the shape of the component, a thirteen-steps cutting processes was proposed, two steps of which are free and open to subsequent changes that can occur in the process of shearing. Normalized components from the catalogue company FIBRO were used in the construction of the pressing tool. The press GERB EDELHOFF 80 t was selected as the working device.

Manufacturing possibilities of the clamping ring part
Dvořák, Jiří ; Peterková, Eva (referee) ; Císařová, Michaela (advisor)
This bachelor work has been elaborated as a part of my bachelor studies of engineering technology and deals with the problem of choosing an optimal method of producing a particular component part named “Clamping ring”. A fundamental emphasis is placed on the economical aspect of the matter while preserving conditions imposed by the client. The component has originally been manufactured by cutting the intermediate out of a sheet metal using a CO2 laser cutting machine, subsequent lathe work, manual boring and creating a thread. This work offers technological alternatives to the manufacturing of the intermediate as well as the following machining. All options are evaluated with regard to the production expenses and lead to a most economically plausible method of manufacturing the entire component part.

Proposal for the production of variants of flat sheet metal parts with holes
Chaloupková, Lucie ; Peterková, Eva (referee) ; Špaček, Jindřich (advisor)
The final work elaborated in the scope of bachelor studies of the branch B2307-00 submitted variants of production for flat sheet metal parts with holes. In work there are two variants of production of one particular part namely: Production on sequence shearing tool and production by means of plasma CNC machine. Particular part is designed for quantity 120 000 pieces per year. Shearing machine S250 with shearing force 2500 kN is selected (manufacturer Smeral a.s.Brno). In the work there are implied necessary calculations for both variants including economical evaluation and criteria for practically implementation.

The manufacturing of level indicator by fineblanking process
Polák, Pavel ; Šlais, Miroslav (referee) ; Peterková, Eva (advisor)
The project elaborated in frame of engineering studies branch 2307. The project is submitting design of technology production of the extract - section from the deep drawing sheet iron 11 373.1. Pursuant to of the literary pursuit a problem of the deep drawing and calculation was designed drawing in instrument with holder. The lower ejector is using for extrusion component. The drawing instrument make use of standardised components and it is solving forms of customary stool close-set on the crank drawing inclinable press LEN 63 C (producer APJ Praha), with nominal tensile force 630 kN. Drawing punch and drawing die are produced from alloyed instrumental steel 19 436.9 (POLDI 2002), heat-worked according to drawing documentation.

The deformation necks and their use in forming technology
Grufík, Lubomír ; Štroner, Marek (referee) ; Peterková, Eva (advisor)
The project which was elaborated in bachelor education presents summary of deformation necks and their use in forming technology. Pursuant to of the literary pursuit a problem of deformation necks in forming technology there were formulated description of given methods, summary of methods spreading of deformation necks on the surface of half-finished products, their assets and use in practice. Then there are conspectus of computer simulation, which is used so to evaluation of deformation and transformation, its advantages and disadvantages in practice.
